**Syntax**

` >> ABSOLUTE`

**Parent Command**

` > PARAMETER`

**Subcommand**

` >>> MATERIAL`

**Description**

This command selects as a parameter the absolute permeability (TOUGH2 variable PER(ISOT,NMAT)) of the specified material. Subcommand `>>>> LOGARITHM` invokes estimation of a single log-value which is assigned to all selected materials; subcommand `>>>> FACTOR` invokes estimation of a common multiplication factor which is applied to all selected permeabilities, thus maintaining the permeability ratios between the materials; subcommand `>>>> LOG(F)` should be used to estimate a log-normally distributed factor with which all the permeabilities are multiplied. By default, the estimate refers to all three flow directions (ISOT=1, 2, 3). Subcommand `>>>> INDEX` can be used to select the permeability of a specific flow direction ISOT.

**Example**
